Other changes in this sumbission include the added ability to tessellate polygons in Collada reader, with appropriate options.
- No tessellation
- Tessellate as triangle fan (previous behaviour, kept as default for backward-compatibility)
- Full tessellation
I also put auto_ptr<> for RAII of DAE structure (as discussed), and moved reader options in a structure, as for the writer.
Code also make use of osgDB::ExternalFileWriter I submitted, so please merge this submission after the PluginImageWriter one.
DAE plugin was linking ORIGINAL images in the Collada file, using image->getName() as a path (even if images were modified in memory!). As the behaviour was not the one of other plugins (3DS, FBX, and such), I made the plugin relativise images filenames (as those plugins) and write the image which is in memory. However, in order to avoid removing features, I kept the previous behaviour but moved it in an option. Here are the options of the plugin I changed:
- daeForceTexture was unclear in this new context and removed in favor of two new options
- daeLinkOriginalTexturesNoForce: Writes reference to the original image if found, instead of writing the image in memory
- daeLinkOriginalTexturesForce: Writes reference to the original image even if not found, instead of writing the image in memory
Of course, if you specify no option, images are written as for other plugins.
Other thing I changed is the UTF8 support as I told you in a previous conversation. Now there is a simple option, "daeNamesUseCodepage", which makes all names except filenames (materials, animation, geometries...) be considered as encoded using current codepage. If so, they'll be converted to UTF8 when writing; else they are written directly. Of course, filenames follow OSG_USE_UTF8_FILENAME as usual.
I did "
osgAnimation. It's been tested with the majority of the samples in the
COLLADA test repository and works with all of them either as well as, or
better than, the version of the plugin currently in SVN.
Known issue: vertex animation (AKA morphing) doesn't work at present,
but that's a relatively unpopular method of animating so it's not high
on my priority list."
Follow up email:
"I've been informed that the previous DAE submission didn't build on
unix, so here's the submission again with the fixes. Thanks to Gregory Potdevin and Benjamin Bozou.
Also, my apologies to Roland for not crediting his part in making DAE
animation happen, my work was indeed built on top of his work. Thanks
also to Marius Heise and of course Cedric Pinson."
Changes by Robert Osfield, fixed compile issues when compile without C* automatic conversion enabled in ref_ptr<>
and constructor initialization fixes to address some warnings under gcc.
